What is 2/20 plus 2/3? (Answer: 23/30)

Exact Answer

==================================================
Problem: What is 2/20 plus 2/3?
Formula / Expression: 2/20 + 2/3
Final Answer: 23/30
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 20 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 20 × 3 = 60.
Working: LCD(20, 3) = 60

Step 2: Convert to Equivalent Fractions with Common Denominator 60
Multiply the numerator and denominator of 2/20 by 3, and multiply the numerator and denominator of 2/3 by 20 so both fractions share the common base 60.
Working: 2 × 3/20 × 3 = 6/60 and 2 × 20/3 × 20 = 40/60

Step 3: Add the Numerators
Now add the numerators (6 + 40 = 46) and keep the common denominator 60 unchanged.
Working: 6 + 40/60 = 46/60

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 46 and 60, which is 2. Divide both the numerator and denominator by 2.
Working: 46 ÷ 2/60 ÷ 2 = 23/30

Step 5: Decimal & Percentage Representation
Dividing the numerator 23 by denominator 30 produces a repeating decimal (approximately 0.766667, or 76.6667%).
Working: 23 ÷ 30 = 0.766667 (76.6667%)

Key Values:
- Simplified Fraction: 23/30
- Mixed Number Form: 23/30
- Decimal Value: 0.766667
- Percentage: 76.6667%

Step-by-Step Solution: 2/20 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 20 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 20 × 3 = 60.

LCD(20, 3) = 60

Step 2

Convert to Equivalent Fractions with Common Denominator 60

Multiply the numerator and denominator of 2/20 by 3, and multiply the numerator and denominator of 2/3 by 20 so both fractions share the common base 60.

2 × 3/20 × 3 = 6/60 and 2 × 20/3 × 20 = 40/60

Step 3

Add the Numerators

Now add the numerators (6 + 40 = 46) and keep the common denominator 60 unchanged.

6 + 40/60 = 46/60

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 46 and 60, which is 2. Divide both the numerator and denominator by 2.

46 ÷ 2/60 ÷ 2 = 23/30

Step 5
